next time you're in a shop with some archery gear grab a few 5 pin type sights and have a look to see what stands out to you more as they typically have green/red/yellow fibre optic pins in one place to see what your eyes will pop best with, people have different eyes, most will find green the brightest with red a closer 2nd and every now and then some guys it's yellow that jumps best for them, I'm a green guy, red works well but if I can get green I do, and they say green best for daylight as well, but you can hold them up in a shop and find varying lighting conditions to see what's popping best at low light as well, end of day red or green likely to work just fine for you but now you know another way to figure out if your eyes have a preference
